RAID-0 or RAID-10

Hi there,

I am willing to buy a new computer mostly used for capturing and editing video..

I am thinking of two options regarding hard drives..

option #1

1 x WD Caviar SE (160GB/8MB Cache) for the OS
2 x WD Caviar SE16(250GB/16MB Cache) in RAID-0 for processing video files.
1 x WD Caviar SE16 (500GB/16MB Cache) for backup and archive.


option #2

4 x WD Caviar SE16 (250GB/16MB Cache) in RAID-10

which option is better in terms of performance and reliability? is there any significant difference between the two configurations

Thanks
